Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Such as Fig. 1, a kind of aviation fuel thief-sampler syringe includes chemical water test device connector 1, the shell 2 with both ends open, has
The transparent liner 3 and piston component of both ends open.1 head of chemical water test device connector is for connecting chemical water test device, oil
Color after product change after chemical water test device according to test paper determines whether boat kerosene product aqueous and substantially water content.Describedization
One end that thief-sampler connector 1 is set to the shell 2 is learned, the liner 3 is placed in the shell 2.Including the piston component energy
It stretches in gallbladder 3, for oil product to be pumped into liner 3 from the chemical water test device connector 1.The shell 2 is along the piston component
Telescopic direction offers form 21.The other end of the piston component and the shell 2 is locked by hold-doun nut 4, described
Hold-doun nut 4 can be by the 3 both ends sealing contact of liner in the chemical water test device connector 1 and the hold-doun nut 4 after locking
Between.When pull piston component, oil product can be entered chemical water test device connector by chemical water test device, be opened later by shell
Mouth, liner opening are by pull into liner 3.Tester can pass through the amount that form checks that oil product is pumped into liner.Accurately to know
Know oil product be pumped into amount, the liner 3 its in the visual position of the form 21 be equipped with scale.
1 bottom of chemical water test device connector is equipped with connection sheet 11(such as Fig. 3), 11 diameter of connection sheet is greater than shell 2
Openings of sizes.The connection sheet 11 is placed in the shell 2, and the chemical water test device connector tip stretches out in outside shell, with even
Connect chemical water test device.The chemical water test device is existing chemical water test device structure, is not described in detail herein.The connection sheet 11
Sufficiently large to cover entire shell aperture, after the hold-doun nut 4 locking, the liner 3 holds out against the connection sheet 11, so that
The connection sheet is close to the shell, prevents oil product excessive.It holds out against to improve liner in the leakproofness of the shell, described
The first sealing ring is equipped between liner 3 and the shell 1, first sealing ring uses rubber seal.Specifically, described
One sealing ring is placed between the connection sheet 11 and the liner 3, convenient for connection sheet 11 described in the liner sealing contact, is prevented
Oil product overflows to come at home and abroad from liner 3.
The piston component includes interior bar 5, piston 6, gasket 7, outer bar 8, handle 9.Described 5 one end of interior bar has screw thread,
With the handle 9 is threadedly coupled, 5 other end of interior bar has top flat 51(such as Fig. 2).The piston 6 and the gasket 7 are equal
It is sheathed in the interior bar 5, and the piston 6 is set between the top flat 51 and the gasket 7.The outer bar 8 is sheathed on institute
It states outside interior bar 5, when the handle 9 locks the interior bar 5,8 both ends of outer bar are held out against in the handle 9 and the gasket 7
Between, and the piston 6 is held out against between the top flat 51 and the gasket 7.The interior bar 5 and the outer bar 8 are from described solid
The through-hole 41 for determining nut 4 extend into the liner 3 and stretches in liner 3, and band piston 6 moves in liner 3.Tester
By the way that handle 9 to be tightened in the end of the interior bar 5, so that handle 9 squeezes outer bar 8 towards at piston 6, until piston is pressed
It is next, it is ensured that piston component can effectively extract oil product.
The piston 6 includes first piston head 61, second piston head 63 and dottle pin 62.The dottle pin 62 is set to described first
Between piston head 61 and the second piston head 63.The first piston head 61, the second piston head 63, the dottle pin 62 are
Single individual components synthesize single-piece piston structure by connection.Squeezing effect is more preferably, more labor-saving in this way, and piston both ends are pressurized
Expansion two is enclosed after power, and sealing effect is more preferably.The piston can also only have one that first piston head and second piston head are constituted
A complete profiled part needs bigger extruding force in this way.The first piston head 61 and the second piston head 63 use rubber
Glue piston head.The dottle pin 62 uses rubber ring.
The liner 3 is glass inner bag, and on the one hand visual, one side wall of inner container is smooth, and resistance is small, in pull piston component
When it is more labor-saving.In addition, glass inner bag easy cleaning, it can Reusability.
It is the shell 2, the chemical water test device connector 1, the hold-doun nut 4, the interior bar 5, the outer bar 8, described
Handle 9 can be used stainless steel material and be made, long service life, durable.5ML graduation mark can be carved with outside the shell.Described
Under conditions of liner scale can not be seen, by shell outside graduation mark quickly extract the desired amount of oil product of detection.
A kind of aviation fuel thief-sampler syringe further includes locking nut 10.The outer bar 8 is screw rod.The locking nut 10 is arranged
In outside the outer bar 8, and 10 outer diameter of the locking nut is greater than 41 openings of sizes of through-hole, and is greater than its lock of the handle 10
The openings of sizes of tight 5 end of interior bar.It is utilizing the locking of handle 10 interior bar 5 that piston top is next, is being revolved using locking nut
To suitable position, handle 10 is limited, handle 10 is avoided to be further threaded into.
It scabbles along its length 8 side of outer bar.The through-hole 41 is the arch hole to match with 8 shape of outer bar.
In this way, can limit outer bar passes through the direction of 4 through-hole 41 of hold-doun nut, and prevent from rotating when pull piston component.Separately
Outside, the side of scabbling of the outer bar is equipped with scale, convenient for accurate sampling.
In order to improve the leakproofness of through hole, second be equipped between the liner 3 and the hold-doun nut 4 is sealed
Circle.Second sealing ring uses rubber seal, can avoid air and enters in draw process from through hole, then influences oil
Product pull effect and precision.
Handle is tightened when use clockwise, holds out against piston, fixed locking nut after air tight.It is loose counterclockwise after use
Open locking nut, release handle counterclockwise.
